+ * Friendship acceptance for DFRN contacts
+ *
* There are two possible entry points and three scenarios.
- *.
+ *
* 1. A form was submitted by our user approving a friendship that originated elsewhere.
* This may also be called from dfrn_request to automatically approve a friendship.
*
* 2. We may be the target or other side of the conversation to scenario 1, and will
* interact with that process on our own user's behalf.
- *.
